  It is the study of the internal structure of organisms.
• Who was Andrea Caesalpine?

  He divided plants into fifteen groups and called them genera.
• What is the androecium in flowering plants?

  It is the male reproductive organ consisting of stamens.
• What are angiosperms?

  They are a diverse group of flowering plants characterized by enclosed seeds within fruits.
• What is the kingdom Animalia?

  It consists of multicellular heterotrophic eukaryotes.
• What is Anopheles?

  It is a female mosquito that spreads the malarial parasite in humans.
• What is the anther in a flower?

  It is the part of the stamen where pollen grains are produced.
• What are antipodals in flowering plants?

  They are three cells in the embryo sac located at the opposite end of the micropyle.
• What is apomixis?

  It is a form of asexual reproduction in plants where seeds are produced without fertilization.
• What are Archaea?

  They are a domain consisting of single-celled prokaryotic organisms.
• What is artificial vegetative propagation?

  It is a method of plant reproduction involving human intervention to produce clones.
• What is the ascent of sap in plants?

  It is the process by which water and nutrients are transported from roots to leaves.
• What is asexual reproduction?

  It is reproduction that does not involve the fusion of gametes, resulting in genetically identical offspring.
• What is autophagy?

  It is a process in which a cell consumes its own damaged organelles.
• What is binary fission?

  It is a form of asexual reproduction in bacteria and some other single-celled organisms.
